I am also worried a bit about knowledge nowadays. With LLM-based AI, should one also store individual chats in personal knowledge system? Yeah, I believe that some my chats are quite full of relevant info, that can be used in the future. Also what is the right general approach here - should I ask the same question several times (every time I need information) or should I just look up previous answer in my history? To be fair I dont store google results, I just search it again, but with chat the path to right answer is often more complex than spitting few words in google search input box.
